[courier-users] Outbound ESMTP STARTTLS unrecognized command

[Marco K. <m.k...@kb...>]

Hello List!

 

I often get:

 

 

                           UNDELIVERABLE MAIL

 

Your message to the following recipients cannot be delivered:

 

< <mailto:act...@al...> activation@xxx>:

    asd.com [1.1.1.1]:

>>> STARTTLS

<<< 500 unrecognized command

 

 

 

Solution ist to add an exception to this domain in outbound esmtp.

 

Any other solutions?

 

 

Thanks!
